The Nightingale (Luscinia megarhynchos), also known as Rufous and Common Nightingale, is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. It belongs to a group of more terrestrial species, often called chats.
It is a migratory insectivorous species breeding in forest and scrub in Europe and south-west Asia, but is not found naturally in the Americas. The distribution is more southerly than the very closely related Thrush Nightingale Luscinia luscinia. It nests on the ground within or next to dense bushes. It winters in southern Africa. At least in the Rhineland (Germany), the breeding habitat of nightingales agrees with a number of geographical parameters.
less than 400 m (1300 ft) above mean sea level
mean air temperature during the growing season above 14 °C (57 °F)
more than 20 days/year on which temperatures exceed 25 °C (77 °F)
annual precipitation less than 750mm
aridity index lower than 0.35
no closed canopy
The nightingale is slightly larger than the European Robin, at 15-16.5 cm (5.9-6.5 in) length. It is plain brown above except for the reddish tail. It is buff to white below. Sexes are similar. The eastern subspecies L. m. hafizi and L. m. africana have paler upperparts and a stronger face-pattern, including a pale supercilium.
Nightingales are named so because they frequently sing at night as well as during the day. The name has been used for well over 1,000 years, being highly recognizable even in its Anglo-Saxon form - 'nightingale'. It means 'night songstress'. Early writers assumed the female sang when it is in fact the male. The song is loud, with an impressive range of whistles, trills and gurgles. Its song is particularly noticeable at night because few other birds are singing. This is why its name includes "night" in several languages. Only unpaired males sing regularly at night, and nocturnal song is likely to serve to attract a mate. Singing at dawn, during the hour before sunrise, is assumed to be important in defending the bird's territory. Nightingales sing even more loudly in urban or near-urban environments, in order to overcome the background noise. The most characteristic feature of the song is a loud whistling crescendo, absent from the song of Thrush Nightingale. It has a frog-like alarm call.
The nightingale is an important symbol for poets from a variety of ages, and has taken on a number of symbolic connotations. Homer evokes the Nightingale in the Odyssey, suggesting the myth of Philomela and Procne (one of whom, depending on the myth's version, is turned into a nightingale ). This myth is the focus of Sophocles' tragedy, Tereus, of which only fragments remain. Ovid, too, in his Metamorphoses, includes the most popular version of this myth, imitated and altered by later poets, including Chrétien de Troyes, Geoffrey Chaucer, John Gower, and George Gascoigne. T.S. Eliot's "The Waste Land" also evokes the Nightingale's song (and the myth of Philomela and Procne). Because of the violence associated with the myth, the nightingale's song was long interpreted as a lament.
